'/'o ZZ whom t may concer/h.:

Be it known that l', Puncv Tom), a subject ot' the King ot Great Britain, residing at (iradsden, in the county of Etoi'ahI and State of Alabama, have invented certainiiew and use'tul Improvements in Reserve-Su ply Drain and Cut-Ott `ValvesA for Liquid- `uel ylanks, ot' which the following is a speci ieation. V

My inventibn relates to a reserve supply valve Jfor fuel il tanks and the like having tor its chief objetsimplieity ot' design and ease ot adaptation 'Into service.A This valve is designed to tit ii'ittybthe fuel tank otl the less expensive cars also motorcycles and) motor boats` without chai e'e in the tankconneetions, and to adapt the present tank to serve the purpose of an auxiliary tank. lts working parts are few and simple and its` manufacture inexpensive while it is designed to serve the threetold purpose ot supplying i'uel to the engine yet withholding a reserve supply in the tank 'for emergency use; ot draining the said reserve supply; and ot' serving as a cut-ott' valve-at any time to prevent the further discharge of the fuel oil fromA the tank.

My invention moreover 'comprises the novel details ot construction and arrangements of parts, which in their preferred embodiment only arb illustrated in the aecompanying drawings, to which reference is made in the following specification, and in Whichz Fig. 1 is a. verticalelevation showing partially in cross sectionthe valve tube and.

tank with the reserve supply drain open.

Fig. 2 is a vertical erosssection ot a similar valve showing theusual filter properly connected therewith.

Similar reference numerals refer to similar parts throughout the drawings.

My invention, as illustrated,l comprises a tank 1 with outlet collar 2 attached thereto.

A bushing 3 cast integral with the body por tion 4 ot the valve, saidlbody portion havingl a hex-shaped collar 5 ,east thereon to lpermit screwing the bushing 3 into the tank bottom. Extending through thebushing 3 is 'a tube (S closed at its lower end and termed into a threaded-rod 7 at its lower end, whereupon the operating lever 8 is attached and keyed by any suitable means andsecured by the lock nut 9. This tube G is of such length as to project upwardly into the tank far enough to 'prevent the complete discharge of the contents ot the tank, i. e., to leave in the tank an emergency reserve up to the liquid level 10. At the base of the bushing 3 l provide a hole 11 which registers withthe-hole 12 in one side ot the tube G. At the lower'nd of the tube 6 are two oppositely disposed holes 13 lying in the same vertical planeas the hole 12 and ,in the sainelhorizontalf plane as the duct 14 which leads through the body 4 to the discharge line 15 yn Fig. 2 l show by very little change in the valve design the interposition ot a filter 16, which is so commonly used on the smaller cars, between the duet 14 and the line 15.

The operation ot the above described valve is indeed simple.. It is assumed that normally the tncl oil in the tank 1 will/.be kept above the level 10 and the tube 6 will be set as shown in Fig. 2, but, should the Viuelrun so low as to stop disehargipgutgom the tank through the open top ei'ilice 1T of the tube 6 and cause the engine to stop, the operator will take heed that his fuel supply is low. Until this time the tube 6" acting as a valve will close the port 11, but this port can be now opened by bringing the hole 12 opposite the hole 11 and thereupon the4 remaining tuel constituting the emergency reserve will be discharged. It will be noted that in both of these positions one or the other ot the h'oles 18 in the bottom of the tube 6 will register with the outlet duct 14. Hove/1 I evt the supply can be stopped entirely at any time by turningl the lever in such position as to blank ott the end ot the duet 14 by throwing the holes 13 outof register therewith, thus my invention serves the threefold purpose of supply. reserve and cut oit'.

Having thus described my invention, what I claim' as new and desire. to secure by Letters Patent, is:-

1. In combination with atuel tank having a bottom opening, a sleeve mounted in said opening and having a port thereindisposed within the tank near its bottom, a

drain tube mounted to rotate in and )rojeeting upwardly through `and above sai sleeve to, and having au upper poi/ft at a predetermined level in the tank, there being an intermediate port in said tubryadapted to register with said 'sleeve port, andfa discharge,- L

of register therewith and one iying ine vertical plane with said intermediate tube port. f

2. A valve adepted'to drain, cui; off and hold en emergency reserve of fuel oil in a tank, comprising a sleeve entering the tank bottom and having intake and discharge lports, an integral tubular valve fitted te rotate in and projecting upwardly to a. predetermined height through said sleeve and having en upper port at its top and en intermediate port disposed to register with the vsleeve intake port and opposite lower ports lying in the same vertical plane with said interrnedizz'e lport and disposed to register with -the sleevesdischarge port as the vaveis ro-- tated,`said lower ports being-spaced to enable the valve to ciose seid discharge port, and means' to rotatel said valve to operating positions connecting the outletand intermedate ports, thel outlet and top orts only, or closing the eutet port, es and) poses described.

In testimonyy whereof I affix my signature. i
